Description

Technical Field

[0001] The utility model belongs to the technical field of speed reducer assembly, in particular to a speed reducer shaft assembly bracket. Background Art

[0002] The transmission shaft is one of the core components of the reducer, and the long shaft assembly process of the split-box reducer is to first install the gear bearing on the reducer shaft, then use the lifting lug or sling to lift the reducer shaft with the lifting machinery, and finally place the reducer shaft on the bearing seat of the reducer by adjusting the horizontal and vertical positions of the reducer shaft. Although the existing assembly bracket will not shake during the rising process, it is still easy for the reducer shaft to fall when it is hit by external force.

[0003] The existing authorization announcement number (CN205290890U) is a reducer shaft assembly bracket, which includes: a support assembly, which is used to position and support the reducer shaft; a vertical lifting assembly, which is connected to the lower part of the support assembly and is used to lift the support assembly in the vertical direction; a bracket base, on which the vertical lifting assembly is installed, and the lower part of the bracket base is provided with walking wheels. During operation, the reducer shaft is supported by two reducer assembly brackets, and the horizontal position of the reducer shaft relative to the reducer bearing is adjusted by moving the bracket base, and the vertical position of the reducer shaft relative to the reducer bearing is adjusted by the vertical lifting assembly, and finally the assembly of the reducer shaft is completed. Compared with the existing assembly of the reducer shaft by the cooperation of the lifting mechanism and the lifting lug or the lifting belt, the reducer shaft assembly bracket in the utility model will not cause the reducer shaft to swing and rotate during the assembly process, and the positioning is stable, which is more convenient for assembly and is not prone to collision and damage of the reducer shaft. Its disadvantage is that although it will not shake during the rising process, the reducer shaft is still easy to fall off when hit by external force, and the reducer shaft is supported by multiple supporting connecting rods. The supporting connecting rods will rust and age due to long-term use, which has a certain impact on the rising of the reducer shaft. Utility Model Content

[0011] As a preferred embodiment, the top end of the threaded rod passes through the rotation opening and is connected to the inner ring of the auxiliary gear, and the outer periphery of the main gear and the auxiliary gear are rotationally connected through a gear belt.

[0012] As a preferred embodiment, a lifting block is connected to one side of the connecting block, a fixing rod is welded between the two connecting plates, and a threaded hole and a sliding opening matching the threaded rod and the fixing rod are opened on the surface of the lifting block.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

A placement frame 19 for placing the reducer shaft is welded at the top and center of the connecting block 18, and a protective pad is laid on the surface of the placement frame 19. Four mounting rods 20 symmetrical to each other are installed on the top of the connecting block 18. The upper end periphery of the mounting rod 20 is provided with an external thread 21, and a limit block 22 for limiting is connected to the top of the mounting rod 20. The limit block 22 is used to limit the lower pressure plate 25. The four mounting rods The outer periphery of 20 is slidably connected with the lower pressure plate 25, and a protective pad is also adhered to the bottom end of the lower pressure plate 25 to protect the appearance of the reducer shaft and prevent bumps. The surface of the lower pressure plate 25 is provided with four lifting openings 24 adapted to the mounting rod 20. The lifting openings 24 are not threadedly connected with the external thread 21 of the mounting rod 20, but are in contact with the smooth outer surface of the mounting rod 20 and are slightly larger than the mounting rod 20. The outer periphery of the external thread 21 is threadedly connected with a rotating button 23 for resisting the lower pressure plate 25, and the bottom end of the lower pressure plate 25 is in contact with the top end of the reducer shaft.

[0027] After the reducer shaft is placed on the placement rack 19, the lower pressure plate 25 slides down along the outer circumference of the mounting rod 20 and rests on the top of the reducer shaft to complete the limiting. Then, by twisting a plurality of rotating buttons 23 and rotating along the external thread 21 of the mounting rod 20, the plurality of rotating buttons 23 rest on the lower pressure plate 25 to complete the fixation.

[0028] This structure can not only fix the reducer shaft, but also fix reducer shafts of different sizes.

[0030] After the fixation is completed, the rotating shaft 9 is driven to rotate by running the servo motor 8. As the rotating shaft 9 rotates, the main gear 10 connected to its outer periphery follows the rotation, thereby pulling the gear belt 12 on the outer periphery of the main gear 10 to rotate, and the sub-gear 11 at the other end drives the threaded rod 13 to rotate as the gear belt 12 rotates. The threaded rod 13 rotates along the rotating opening 5 of the support plate 3. The sub-gear 11 drives the lifting block 15 connected to the threaded rod 13 to rise, and the lifting block 15 slides along the outer periphery of the fixed rod 14, and then the reducer shaft placed on the top of the connecting block 18 connected to it is lifted and lowered.
